A method of producing a flexible film laminate and a flexible film laminate produced
thereby |
(57) A flexible film laminate is produced by bonding a first layer of a heat-sealable
polyolefin film to a second layer of a polyacrylonitrile homopolymer film by way of
a third layer of a syndiotactic poly-1,2-butadiene adhesive interposed between the
first and second layers. The bonding is effected in the presence of free radicals
generated at least at the interface between the second and third layers.
